I'd have to go look, used a step drill, went I step up. slid them on, fit over the shoulders of the wheel studs. In hindsight I may have been able to replace wheel studs with something without the shoulder.
Good to have this sorted out while I had things apart to change the gears from 3.73 to 4.10 which will work better with the rest of the powertrain here in the Blue Mountain of N.E. Oregon!

Should have everything ready to go once the snow melts, which isn't the direction things are going now.
